train zero123 yields rotating video but export has no vertices and faces

[createthis]

I have a very simple pixel art sprite image from an old 2d game project:

I successfully created the 3d rotating video using zero123:

python launch.py --config configs/stable-zero123.yaml --train --gpu 0 data.image_path=./load/images/walking1.png

it300-val.mp4

However, when I try to export the mesh:

python launch.py --config configs/stable-zero123.yaml --export --verbose --gpu 0 data.image_path=./load/images/walking1.png system.exporter_type=mesh-exporter

... it doesn't seem to think the mesh has vertices or faces:

I'm on Windows 10 and I'm using a 3090 RTX.
Python 3.10.11
pip 23.3.2 from C:\Users\jesse\Documents\ai\threestudio\venv\lib\site-packages\pip (python 3.10)

Compiling nvdiffrast_plugin and getting it to work, such as it is, was a challenge:

• ImportError: No module named 'nvdiffrast_plugin' NVlabs/nvdiffrast#46 (comment)
• ImportError: No module named 'nvdiffrast_plugin' NVlabs/nvdiffrast#46 (comment)

Anyway, please let me know if you have any ideas for further debugging.

nvm, this was user error. I failed to read the instructions and used data.image_path instead of resume. Here's the updated working command:

python launch.py --config configs/stable-zero123.yaml --export --gpu 0 resume=outputs/zero123-sai/\[64\,\ 128\,\ 256\]_walking1.png\@20240126-111928/ckpts/last.ckpt system.exporter_type=mesh-exporter

Very cool stuff! Closing!
